NO
When users are mapped to a shared schema, the utility
tries to drop their local schemas from the database. If this
parameter is set to NO, then users are migrated only if
they do not own objects in their local schema. Users who
own objects in their old local schemas do not migrate and
produce an error message in the migration log file.
YES
If this parameter is set to YES, then all users' schema
objects are dropped along with their local schemas when
they are migrated. Privileges and roles that were
previously granted to the users are also revoked.
(These values are not case-sensitive.)
NO
Specifies whether a user's local schema is dropped when the
user is mapped to a shared schema.
This parameter is effective only when MAPSCHEMA is set to
SHARED.
Distinguished Name (DN) of the parent for user entries. This
is the same as the user search base or user create base in an
Oracle Internet Directory identity management realm.
Parent DN can also be specified within double quotation
marks ("...").
